BED-BOTTOM.

Specification of' Letters Patent.

Patented Nov. 20, 1906.

Application filed January Il, 1905. Serial No. 240,602.

To {ir/ZZ whom, it Wwf/y concern:

Be it known that I, ELIAS A. CLEAVELAND, a citizen of the United States,residing at Belvidere, in the county of Boone and State of Illinois,have invented certain new and useful Improvementsl in Bed-Bottoms, ofwhich the following is a specification.

The object of this invention is to construct a bed-bottom in which theend bars are connected by tubular side bars let into the end bars,thereby producing a strong and rigid frame.

The further object of this invention is to provide means located beneaththe wire fabric of the bed which impart additional strength to thefabric.

In the accompanying` drawings, Figure l is an under face representationof a bed-bottom containing my improvements. Fig. 2 is a lengthwisesection on dotted line a o, Fig. 1. Fig. 3 is a transverse section ondotted line b I), Fig. 1. Fig. 4 is aperspective view of a section ofone of the end bars. Fig. 5 is a perspective view of a section of one ofthe tubular side bars.

The end bars I and 2 are formed of wood, and near the ends of each areformed semicircular cavities 3. Tubular side bars 4 and 5 have theirends closed, and each end has a perforation 6. The end sections of thesetubular side bars are located in the semicircular cavities 3 in thewooden end bars l and 2 and are secured in position by the bolts 7.

The side bars being tubular, they will impart the necessary strength tothe structure, and their ends being let into the wooden end bars willhold the frame from racking. A single bolt in each end of the tubularside gars will serve to connect them with the end ars.

The wire'fabric 8 is connected to the end bars of the frame in the usualmanner. Beneath the wire fabric and supported by the end bars of theframe are located a series of additional supports for the fabric, and asall the supports are the same in construction a description of one willanswer, In the end bar 2 of the frame is turned a screw-eye 9, and inthe end bar l is turned a screw-eye 10.

A screw-hook 1l has a connection with the screw-eye 9, and a screw-hookl2 has a connection with the screw-eye 10. An equalizing-bar 13 has aconnection with the screwhook Il, and a nut 14 holds it in engagementtherewith. The ends of this equalizing-bar are in hook form. A yieldingequalizingbar is formed with wire having l5 and its branches extendingfrom the coil having hooked ends. Within the coil of the yieldingequalizing-bar is located a stud I6, provided with a transverse opening17 and a head 18 on its end opposite to the end having the opening. Thescrew-hook 12 is located in the transverse opening 17, and a nut I9 1splaced on the screw-hook. Two stay-wires 20, connected to helicalsprings 21, have their ends connected to the equaliZing-bar and to theyielding equalizing-bar.

By means of the helical springs and the spring action of the yieldingequalizing-bar the wire fabric is supported in a flexible manner, and bymeans of the nuts I4 and 19 the tension of the helical springs and ofthe yielding equalizing-bar can be adjusted to suit the weight of theperson occupying the bed.

By locating a series of these supports beneath the wire fabric of thebed and each support independently adjustable should two persons ofdifferent weights occupy the bed each side can be adjusted independentof the other side, so that bothpersons will lie on the same level.

The construction of the frame of the bedbottom herein shown anddescribed is not claimed herein, but forms the subject-matter of adivisional application, filed September 27, 1906, Serial NO. 336,428.

' I claim as my invention- 1. A bed-bottom composed of end and sidebars, an equaliZing-bar supported by a screw hook and eye connectionwith one of the end bars, and having its ends in hook form, thescrew-hook passing through the equalizingbar and having a nut on itsend, and helical springshaving a connection with the equalizing-bar andwith the other end bar.

2. A bed-bottom composed of end and side bars, a yielding equaliZing-barcomposed of wires having a center coil and two extending branches,connections between the branches and one of the end bars, a headed studlocatedin the coil, a screw-hookhaving a connection with the stud, a nuton the screw-hook, and a screw-eye connection with the other end barwith which the screw-hook engages.

3. The combination of a bed-spring, an equaliZing-bar, two wiresconnected to the equaliZing-bar, a rod for each equalizing-bar extendingthrough the center portion of the bar, an adjustable nut on one end ofsaid rod,

a center coil a connection between the rod and one end l ing-barextending through the center portion bar ofthe bed-spring7 and the wireshaving a ofthe bar, an adj usting-n'ut on the inner proconnection withthe other end bar. jecting end of each rod, and a connection be- 4. In abed-spring, the combination with 1 tween the other projecting end ofeach rod 5 a frame, and a sheet of flexible material and one oftheframe-bars.

stretched between the frame-bars, of two ELIAS A. CLEAVELAND wiresconnected with one frame-bar and arranged in sets, equaliZing-barshaving their Witnesses: ends connected with the respective wires of E.BEHEL, to a corresponding set, a rod for each equaliz- A. O. BEHEL.
